The Clearinghouse on Assessment and Evaluation (Ericae.net) is a comprehensive online resource dedicated to advancing knowledge in educational assessment, evaluation, and research methodology. Whether you are a student, educator, researcher, or policymaker, Ericae provides the tools, insights, and guidance needed to understand how learning is measured—and how those measurements can be used to improve outcomes.
At its core, Ericae is built to bridge the gap between theory and practice. You’ll find foundational content that explains essential concepts like validity, reliability, and different types of assessment, alongside more advanced material covering psychometrics, data analysis, and research design. For those actively working in education, the site also offers practical strategies for classroom assessment, program evaluation, and data-driven decision-making.
Ericae goes beyond traditional content by serving as a true resource hub. Visitors can explore curated reading paths through the Assessment Library, access peer-reviewed research from the Practical Assessment, Research & Evaluation (PARE) journal, and utilize tools like the Test Locator and ERIC database guides to find high-quality academic resources. Downloadable templates, rubrics, and evaluation tools are also available to support real-world application.
As education continues to evolve, Ericae remains focused on the future—covering topics like digital assessment, artificial intelligence, equity in measurement, and responsible data use. The goal is not just to inform, but to empower users to make better decisions, design better assessments, and contribute to more effective and equitable educational systems.
Whether you’re just getting started or looking to deepen your expertise, Ericae is your trusted guide to understanding and improving educational assessment and evaluation.
